<p>Disclosed is an emergency broadcast receiver. The receiver comprises an alert device, a tuner adapted to demodulate a baseband signal from a radio frequency signal, a signal decoder adapted to extract digital data from the demodulated baseband signal, a location device adapted to provide location data representing a location of the emergency broadcast receiver; and an embedded controller. The embedded controller is adapted to detect a trigger signal in the extracted digital data, determine whether location information encoded in the detected trigger signal corresponds with the location data; and activate, based on the determination, the alert device.</p> |
